代谢性疾病的特征通常是不同组织中的昼夜节律失调,但组织时钟之间的协调和通信如何改变与特定的致病机制有关,在很大程度上仍然未知。应用综合系统生物学方法,我们进行了24小时代谢组学分析8小鼠组织同时进行。我们提出了一个时间和空间图谱的昼夜代谢的背景下,系统的能量平衡,并在慢性营养应激(高脂饮食,HFD)。比较分析揭示了组织代谢的库是如何与特定的时间窗口相关联和门控的,以及这种高度专业化的组织时钟之间的通信和一致性是如何通过营养挑战重新连接的。总的来说,我们说明了如何在时间和空间上重建动态代谢关系,以及如何整合来自多个组织的昼夜代谢组学数据可以提高我们对健康和疾病的理解。在标准和高脂肪饮食下,8种不同组织的昼夜代谢产物谱揭示了组织时钟之间高度专业化的通信和一致性,以及营养挑战如何重新连接。
Metabolic diseases are often characterized by circadian misalignment in different tissues, yet how altered coordination and communication among tissue clocks relates to specific pathogenic mechanisms remains largely unknown. Applying an integrated systems biology approach, we performed 24-h metabolomics profiling of 8 mouse tissues simultaneously. We present a temporal and spatial atlas of circadian metabolism in the context of systemic energy balance, and under chronic nutrient stress (high fat diet, HFD). Comparative analysis reveals how the repertoires of tissue metabolism are linked and gated to specific temporal windows, and how this highly specialized communication and coherence among tissue clocks is rewired by nutrient challenge. Overall, we illustrate how dynamic metabolic relationships can be reconstructed across time and space, and how integration of circadian metabolomics data from multiple tissues can improve our understanding of health and disease. Circadian metabolite profiles of 8 different tissues under standard and high fat diet uncovers highly specialized communication and coherence among tissue clocks and how this is rewired by nutrient challenge.
